Create a SavingsAccount Class

Looking for even more practice building an object hierarchy in Python? Great!

Extend the BankAccount Class

• First, modify the existing BankAccount class to include an additional attribute called has_overdraft.
  • This attribute should accept a Boolean value (True or False).
  • It should default to False if no value is provided during instantiation. This requires using a default parameter in the class’s constructor.
• Adjust the withdraw method to check the has_overdraft status.
  • If has_overdraft is False and the withdrawal amount exceeds the balance, deny the withdrawal and return an appropriate message.
  • Otherwise, if has_overdraft is True, deduct the amount from the balance and return the new balance.

Create a SavingsAccount Class

• Next, create a new SavingsAccount class that subclasses the BankAccount class.
  • This new class should specialize the withdraw method. In the SavingsAccount class, override the withdraw method so that it no longer accepts any arguments, does not change the account balance, and returns the message "No withdrawals permitted".
